Which expression gives the angular positions of the minima in the Fraunhofer diffraction pattern produced by a single slit of width aa illuminated by light of wavelength λ\lambda? a) acos⁡θ=mλa\cos\theta = m\lambda b) asin⁡θ=mλ2a\sin\theta = \dfrac{m\lambda}{2} c) asin⁡θ=mλa\sin\theta = m\lambda d) asin⁡θ=(m+12)λa\sin\theta = (m+\tfrac12)\lambda
